6. 每個(gè)人每晚都要睡夠七八個(gè)小時(shí)

Everyone’s sleep needs are different, and the quality of your sleep matters more than how much time you spend asleep. That said, the National Sleep Foundation offers recommendations based on age group, from newborns who need 14-17 hours of sleep each day to adults 18-64 who should get 7-9 hours each day, and older adults who should get 7-8 hours each day. Children generally need more sleep. A Jawbone study found that people who sleep 8-9.5 hours each night report happier moods the next day.
每個(gè)人的睡眠需求是不一樣的，你的睡眠質(zhì)量比睡覺時(shí)間長短重要得多。因此，國家睡眠基金會根據(jù)不同的年齡段提出建議，新生兒每天需要14-17小時(shí)的睡眠，18-64歲的成人每天7-9小時(shí)，年齡更大的人每天7-8小時(shí)。孩子一般需要更多的睡眠。Jawbone公司的一項(xiàng)研究發(fā)現(xiàn)每晚睡8-9.5個(gè)小時(shí)的人第二天情緒會更好。
